Riemann conjecture, that is, the distribution of prime numbers, ultimately boils down to the zero point problem of the so-called Riemann zeta function.

1859, Riemann made such a conjecture in the article "The number of prime numbers under a given size": all zeros of the zeta (z) function between 0≤x≤ 1 are above Rez =1/,that is, the real part of the zero is1/.
